Appropriate stack sizes become critical on small memory targets and may become highly dependent on the application. It would be wrong to _force_ the developer into using certain stack sizes. Nevertheless, it would be helpful for new users to be able to build some tests easily. One possibility is a "Constrain stack sizes" CDL option in the platform HAL or variant HAL which 'requires' certain stack sizes. It could be enabled by default to help new users and then disabled when users gain more experience and can make decisions for themselves. -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
